Testing starter solenoid

Got my 460 gas home and now to sort out everything that's wrong.

I poured some Marvel oil into all the cylinders and everything cranks by hand nice and smooth. I put a battery on it and nothing. Tested the key switch and that seems to be good, however the starter switch was inop. Can I short from the battery to the center post of the solenoid without damaging anything to test that? I'm trying to get as many parts ordered at once so I can actually accomplish something. I tested the starter and that was good at least.
 
A solenoid should have 2 big posts which are the battery post and the starter side post. Then it should have one or 2 smaller post. The smaller post that goes back to the starter switch you can use a jumper to the battery post to see if the solenoid works. Some solenoids have a ignition post on then to by pass the ballast resister if it has one so as to give the system a hooter spark for start up and if it has that it is not the post you need to jump to test to solenoid
 

Thanks, I just didn't want to break anything and wasn't positive. Better to look dumb asking than to look dumb with broken parts! Solenoid tested good.
 
If it has a "Ford" type solenoid with the two small terminals labeled S and I, if you jump a hot 12 volts to the S terminal it should pull in. If it ONLY has one small terminal, 12 volts jumped there should pull it in. The source of 12 volts can be the big post where the cable down from the battery connects. The other big cable goes to the starter which is hot when the solenoid engages. NOTE this is for solenoids that use the frame as ground connection. Some solenoids have two small terminals, Hot and Ground, that don't use the physical mounting as frame ground I HAVE NO IDEA WHAT TYPE YOU HAVE

If battery voltage is low orrrrrrrrrrr a battery or cable connection is bad, the solenoid may "chatter"

It always good practice if in doubt to remove, clean n wire brush and reattach each n every battery and starter and solenoid and especially ground connection when you have starter problems
